Answer:
The 5' to 3' direction of one strand runs counter to the 5' to the 3' direction of the other strand.
Explanation:
Antiparallel strands of a DNA molecule means that the phosphate groups at the start of two DNA strands are in opposite position (pole).
The DNA molecule is composed of two strands held together by hydrogen bonds. A single strand is different at its two ends. One end is called 5' (5 prime), the other is called 3' (3 prime). The names come from the notation for the two sugar carbon atoms which participate in the phosphodiester bonds. The different strands in the helix run in opposite (anti-parallel) directions. At each end of the double helix, one strand is 5' and the other is 3'.

in a eukaryotic cell, where does transcription occur?
Answer:
transcription occurs in the nucleus, and translation occurs in the cytoplasm.
Explanation:
Stella described protein synthesis as a process that makes the necessary proteins for the human body to function. She
explained the process in the following steps.
1. DNA is transcribed into mRNA.
2. Amino acids form a chain.
3. The amino acid chain is folded into a protein in the endoplasmic reticulum.
What step did Stella miss in her explanation?
(1 point)
O Polypeptide chains express gene traits.
O tRNA delivers the DNA to the ribosome.
hy
O DNA is replicated into two daughter cells.
O mRNA is translated into amino acids.
The step of protein synthesis missed by Stella would be the translation of mRNA into amino acids.
The process of protein synthesis can essentially be divided into 2, namely:
TranscriptionTranslationDuring transcription, genetic information on DNA is transcribed into mRNA. Once this is done, the genetic codes in mRNA are then translated to their respective amino acids and linked by peptide bonds.
The polypeptide bond undergoes further processing such as folding in the endoplasmic reticulum.
Thus, before amino acids can form a polypeptide chain, they must first be translated from genetic codes in mRNA.

Help me with this last thing for my environmental science class
Answer:
1. Energy is passed between organisms through the food chain. Food chains start with producers. They are eaten by primary consumers which are in turn eaten by secondary consumers and them by other consumers.
2. Producers are living things that use energy to make food. Producers make food for themselves and other living things.
3. the difference between a herbivore and an omnivore is a herbivore eats only plants or producers, and an omnivore eats both plants, and other animals/consumers.
4.A food chain follows one path of energy and materials between species. A food web is more complex and is a whole system of connected food chains. In a food web, organisms are placed into different trophic levels.

The main function of the Rough Endoplasmic Reticulum is the production of membrane and proteins secreted by the cell.
What is Endoplasmic Reticulum?The endoplasmic reticulum serves as the transport system of the eukaryotic cell, with many other important functions such as protein folding. It is a type of organelle made up of two subunits –
1. Rough endoplasmic reticulum (RER)
2. Smooth endoplasmic reticulum (SER)
It has a continuous nuclear envelope. The endoplasmic reticulum contains ribosomal granules anchored to the cytoplasmic surface of the cisternae is involved in the synthesis and secretion of proteins through membrane-bound vesicles called ergastoplasms.
Thus, the main function of the Rough Endoplasmic Reticulum is the production of membrane and proteins secreted by the cell.

what happens when the epiphyseal plate is ossified
Answer:
Bones grow in length at the epiphyseal plate by a process that is similar to endochondral ossification. When cartilage growth ceases, usually in the early twenties, the epiphyseal plate completely ossifies so that only a thin epiphyseal line remains and the bones can no longer grown in length.
How do the properties of water and the ability to modify the rates of chemical reactions enable living things to carry out functions necessary for life, such as digesting food?
Answer:
A chemical reaction is a process that changes some chemical substances into others. It involves breaking and reforming chemical bonds. They follow the Law of Conservation of Matter.
Explanation:
Energy is a necessity for all living organisms to survive, and ATP is a reactant that powers several other chemical processes inside cells. Cellular respiration is the method used by cells to produce energy.
What attributes of water are requisite for an organism?The term “universal solvent” refers to water's enormous capacity to dissolve a wide range of molecules, and it is this capacity that makes water such a priceless life-sustaining agent.
Water has five key characteristics: strong polarity, high specific heat, high heat of vaporization, low solid density, and affinity for other polar molecules.
The process of converting one chemical substance into another is known as a chemical reaction. Chemical bonds are broken and rebuilt in this process. The Law of Conservation of Matter is observed by them.
Therefore, Water's function as a solvent aids cells in the transfer and utilization of chemicals like oxygen and nutrients on a biological level.

What happens when oxygen, carbon dioxide and glucose molecules diffuse across the cell membrane? Explain in your own words
Answer:
Simple diffusion is responsible for the spread of an air freshener through a room, or of a few drops of dye to eventually turn a glass of water a uniform color. Molecules naturally disperse from areas of higher concentration to lower concentration.
As oxygen-rich (and carbon dioxide-poor) blood travels by a cell the oxygen diffuses through the cell membrane to the area of lower concentration inside the cell. It can do this easily because the oxygen molecule (O2) is very small and has no charge or polarity. The oxygen is used up rapidly by mitochondria. This rapid consumption causes oxygen to constantly move into the cell from the blood.
